FEED MEANS Eon. FILM-Disks.

Application led September 22, 1916.

To all whom t may concern:

Beit known that I, FREDERICK E. Kennin,

a citizen of the United States, and a resident of Toledo, in the countyof Lucas and State of Ohio, have invented a certain new Y Film-Disks;and

and useful Feed Means for i I do" hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled' -in the art to which it appertams to make and use thesame, reference being had to the accompanying drawings, and to thecharacters of reference marked thereon, which form a part of thisspecification.

This invention relates to movingpicture machines both of the projectingand taking type, and particularly to machinesof this character employingfilms of disk form. The primary object provision inV a machine of thecharacter described of improved meansfor imparting intermittentfeeding'movements to the lm to successively move the picture panels inregister with the projecting or receiving whereby to enhance thepracticability and commercial value of such machines. Further objectsand advantages of the invent-ion will be apparent from the followingdetailedy description thereof.

While the invention, in its broader aspect, is capable of embodiment innumerous illustrated in the accompanying drawings, in which- Figure 1 isa plan view of a machine enibodying my invention, with the inclosingcase in horizontal section. Fig. 2 is a section thereof on the line 2 inFig. 1. Fig. 3 is an enlarged perspective view of the film feedingmechanism embodying my invention. Fig. v4 is an enlarged sectionon theline 4-4 in Fig. 3and Fig. 5 is an elevation of the film engaging endportion of the feed lever with a part broken away.

Referring to the drawings, 1 designates the case of the machine, in thebottom of which are mounted a. pair of spaced parallel rails 2, 2forming a horizontal track on which the wheels 3 of the carriage 4 aremounted for movement to permit a free horizontal reciprocation of thecarriage relative to the case. A shaft 5 is journaled in the carriage 4transversely thereof' and has' one end projecting from the carriage andprovided with opposed clamping members Specication of Letters Patent.

of my invention is thel film-disk 7 Serial No. 121,576.

6 between which a film disk 7 may bermovably clamped to have turningmovements with the shaft and transversel move- The picture panels of thefilm-disk 6 are successively arranged in spiral order on the fact of thedisk, as illustrated in Fig. 2, and as well understood in the art. It istherefore evident that when the disk is rotated to either move thepictures thereon in successive order past the projecting opening, whenthe machine is being used for display purposes, or to bring position forreceivin ing pictures, the dis an image, when takcan be movedtransversely von its axis at proper speed to allow for the properarrangement of vthe picture panels. In other words, the transversemovement of the film must be such as to permit the picture projecting orreceiving opening to move radially of the film as it follows the spiralcourse of the pictures.

In one end of the case 1 is mounted a shaft which carries the operatingcrank 8 without the case. A train of gears 9 connects the crankshaftwith a shaft 10, which is mounted lengthwise of the'case in advance ofthe path of transverse movements of the and has one end journaled in abearing arm 11 projecting from the adjacent case side, and with itsother end journaled in a suitable bearing in one end of the case.

The shaft 10 carries a bevel-gear 12 at its inner end in mesh with alargervbevelgear 13, which is carried by a shaft'14, that is journaledin the upper endof a bearing standard 15 in the horizontal plane of theshaft 10 and at right fangles thereto, the gear 13 being disposed at theend of the shaft 14, which is adjacent to the film-disk 7 The Astandard15 fixedly rises from the bottom' of the case 1 and has its upper endforked, with the shaft 14 extending across the forked opening andjournaled in both furcations Patented Jan. 22,1918.

successive panels into in a bearing head 17 havand lever 26 and acts tonormally urge an naled in the bearing head 17 lengthwise of its carryingarm and in position to stand in axial register with the shaft 10 whenthe bearing arm has been swuno into suitable position therefon The shaft19 carrles a bevel-gear 20 0n its inner end in mesh with the bevel-gear13 and of the same size as the gear 12, thus causing like rotation to becommunicated to the shaft 19 from the shaft 10 through the medium of thegears 12, 13 and 20. A cam-wheel 21 is mounted on the outer end of theshaft 19 and has a protuberant portion 22 on its periphery for thepurpose hereinafter described. The shaft 19 has an eccentric portion 23within the opening 18- in the bearing head 17, and this eccentricportion turns within a yoke 24, that is carried at the inner end of astub-shaft 25, which projects horizontally toward the Elmdisk 7 througha registering bearing in a side wall of the bearing head 17, 'as bestshown in Figs. 3 and 4.

A film feeding lever 26 is mounted on thel outer end portion of thestub-shaft 25 for rocking movements relative thereto and has its filmengaging arm projecting horizontally to a point between the gear 13 andthe film-disk 7 and provided at its outer end with a transverselyprojecting finger' 27,

the outer end of which is socketed to receive a film engaging member 28of rubber or other suitable material for frictionally engaging the filmside and imparting feeding movements thereto as the feed arm issuccessively rocked, as hereinafter described. A coiled compressionspring 29 encircles the stu -shaft 25 between the bearing head 17outward movement of the lever 26 toward the lm 7. At each revolution ofthe shaft 19, the eccentric 23 causes the shaft 25 and lever 26 to bedrawn inward to film releasing position and then permits an outward filmengaging movement of the lever under the influence of the spring 29.rlhe tail-end 26a of the lever 26 terminates over the camwheel 21 andcarries a roller 30 in position to be engaged by the protuberant part 22of the cam-wheel at each revolution thereof. A coiled contractile spring31 connects the tail-piece of the lever to the head 17 and normallyretains the lever with its rear end or tail-piece 26a lowered in stopcontact with an adjusting screw 32, which threads up through the outerend portion of the 'bearing head 17 and is adjustable to vary the normalposition of the lever with .respect .to the cam-wheel 21. At eachrevolution of the cam-wheel, the peripheralv projection 22 thereonengages the lever roller 36 and imparts a film feeding movement to thelever 26 against the tension of the spring 31. The engagement of the camprojection 22 with the lever roller 30 is-so timed with respect to thereciprocatory movements of the lever i intense v carrying shaft 25 thatthe working end of is at the limit of its outward movement with respectto the bearing head 17, or in other words, when the lm wiping member 28of the lever is in engagement with the thus causing a normal feedingmovement to be imparted to the film-disk by the downward wiping actionof the feed member 28 thereagainst. Y

A segmental rack-bar 33 is pivoted at its upper end to a side of thebearing head 17 at its outer end, as by a screw 34, and projectsdownward and inward ,through the lower portion of the standard 15 andhas its rack-teeth, which'are provided on the upper surface thereof, inmesh with a pinion 35, which pinion is mounted on a shaft 36, that isjournaled in the standard 15 and has one end projecting outwardtherefrom through a side of the case 1 and carrying a hand-wheel 37 atits outer end. 1t is evident that a turning of the shaft 36 and pinion35 will impart longitudinal movement in one direction or the other tothe rack-bar 33 and a corresponding raising or lowering of the bearinghead 17 with -respect to the said axis, so that the feed lever, whenswungv downward in film feeding direction, will have a movement which isconcentric to the film axis and which, in addition to imparting a'turning movement to the film, also draws the film and its'feedingcarriage 4 slightly to the right to compensate for the spiralarrangement of the picture panels.

It is evident that the speed of transverse movement of the film-diskdepends on the inclination of the lever 26 with respect to the plane oftransverse movement of the film axis and that an adjustment ofthebearing arm 16and parts carried thereby is effected for this purpose bya turning of the shaft 36 and pinion 35.

The film-disk 7 is pressed or held firm in opposition to the point ofengagement of the same by the feed lever26 by a pressure pad 38, whichis carried at the free end of an arm,39, that projects from a shaft 40,which shaft is suitably journaled in vertical position within theadjacent end portion of the case. A coiled contractile spring 41connects a tail-piece 42 on the arm 39 to an adjacent portion of thecase l andacts on said arm to retainthe pad 38 inyielding contact withthe rear side of the film. The film pressing movement of the pad 38 islimited, however, by a stop-pin 43, which is jection positioned to havestop contact with the tail-piece 42, as shown in Fig. 1. The'pictureimage is transmitted to the ilm or projected from the same through anopening 44 in the pad 38, said opening being properly positioned and ofsuitable size for the picture panels in the film to successively moveinto register therewith as the film is rotated. When the 'film-disk 7 isat rest, it is firmly held to the pad 38 by a pressurefoot 45, which iscarried at the outer end of one arm of a bell-crank lever 46 and has anopening 47 therein in register with the opening 44 in said pad. Thelever 46 is fulcrumed to a bearing arm 48 projecting from the adjacentcase end and has one arm projecting at the outer side of a cam-disk '49on the shaft 10 in position to be `engaged and rocked by a camprojection 50 on the adjacent cam face at each revolution of said shaft.coiled contractile spring 51 connects the le-.f'er 46 to a stationaryplate or member within the case and acts to normally move the lever 46to retain its pressure-foot 45 in Contact with the lm and its other armin the path of movement of the cam projection 50. As the cam pro- 50strikes the lever 46, the lever is rocked to release lthe engagement ofthe pressure-foot 45 with the film and this releasing movement is timedto. take place immediately prior to the film feeding movement of thefeed lever 26, the pressure-foot being held outward from the film duringsuch feeding movement.

In the present instance, the large bevelgear 13, in addition to servingas a driving connection between the gears 12 and 20, is utilized as theshutter member of the ma-` chine and for such purpose is provided with-two openings 53 in its web portion at opposite sides of its center,which openings 'are successively brought into register with the openings44 and 47 in the pad 38 and pressure-foot 45, respectively. The gear 13is of suitable size with respect to the gears 12- and 20 to turn oncefor every two revolutions of said other gears so that one of theopenings 53 is brought into register with the projecting openings of themachine during each half revolution of the shutter gear.

The member 52 above referred to, in the present instance, constitutes alight protector plate which is disposed between the shutter gear 13 andthe film and is provided with an opening therethrough in register withthe line of transmission of the picture ima es.

gIn the use of my improved machine, a film-disk 7 is first clamped tothe shafty 5 -and the carriage moved to the left in posipanel 1n theouter to move mto regprojecting openings tion for the last pictureconvolution of the seri ister with the picture when the film is rotatedin lfeeding direction. Upon a turning of the operating crank 8, a rapidvrotation is communicated to the shaft 19 from the shaft 10 through` themedium of the gears 12, 13and 20, there- 70 by causlng the eccentric`23in conjunction with the spring 29 to impart both an inward and outwardmovement to the feed lever 26 with respect to the film-disk 7 at eachrevolution of the shaft 19 and also to 75 cause the cam-wheel projection22 to act on the outer end of the feed lever 26 to impart a quickdownward rocking'or film feeding movement to the opposite end thereofagamst the tension of the spring 31, which 8o feedmg movement takesplace during the period that the lever is held upward` by the eccentric23 with its wipermember 28 in contact with the lm. It isv thereforeevident that the lever 26 has compound move- 85 ments imparted theretoat each revolution 0f the shaft 19, which movements coperate to move thelever into lm engaging position, to then impart a feedingv or turningmovement to the film whereby a succeeding 9`0 picture panel thereon ismoved into projecting position, and then to retract the lever from filmengaging position. The setting of the rocking axis of the lever 26 belowthe horizontal plane in which the lm ye5 axis and the lever wipermember-28, when elevated, are disposed, causes the downward wiping orfeeding action of the member 28 on the lm to impart not only a rotaryfeeding movement to the film but to draw it slightly forward or to theright to allow for the gradual inward working of the film panels towardthe center of the film due to the spiral arrangement of such panels. It

is evident that as the convolutions of the picture panels become shorteror of less diameter, the forward feeding of the film must becorrespondingly increased 'and this, in the present instance, isaccomplished by the operator slightly turning the control shaft 37 atfrequent intervals so as to increase the incline of the feed finger. Ateach down ward rocking or feeding movement of the lever 26, thepressure-foot lever 45 is swung outward from engagement with the film byVthe coaction of the cam projection 50 withV the lever 46. In order tofacilitate an insertion of a film-disk 7 between the pressurepad 38 andlpressure-foot 45, the shaft 40, which carries the pressure-'pad arm 39,is 120 projected without the case 1 and carries a hand-control wheel 54,thus enabling the operator to turn said shaft and swing the pressure-pad38 outward away from the film against the tension of the spring 41 when125 desired.
